    Under BIOS settings, it might be helpful to see what it shows under "Advanced > Bus Options"

    Other than that it seems to be a pretty bare bones BIOS, not much in terms of settings.
    If there is no option to enable or disable the IDT 92HD73E Audio sound chip there then your options are limited.

    You might try performing a ClearCMOS procedure to see if you can reset the BIOS to re-engage the sound chip.
    This procedure will not affect your Windows installation or any of your files, it is purely motherboard specific and fairly safe for anyone to do if the instructions are followed.

    The instructions for your motherboard are here:
    HP Support document - HP Support Center
    scroll about half way down to find the instructions.
    The location of the jumper is not made clear in the instructions, it may take some searching to find it.

    If that procedure does not revive the sound chip then it may be likely that a defect is the cause, as tacoban pointed out.

    Here's a long shot:
    Check in Windows Services and see if the "Windows Audio" service is running and set to Automatic.

    A supplement to the above post: you could try a simple BIOS Defaults reset first to see if that re-enables the chip.

    If it does, download them, and install, then reboot . Just an idea.

    I went to the page you provided, trying to manually search all the driver but I don't know how to do it. HP first ask me to input my desktop's model number and I did as it said. Then HP told me that windows update may solve the driver problem. But as I mentioned in this post few floors before, windows update said there are nothing to update.

    U can open the case and check if u have a pci sound device or onboard device. U can allso check on HP support site, according to your serial number what type mainboard and sound device is used.
    If u are not sure, write here your pc's model/serial number so we can check what type mainboard/sound device or drive it uses.

    I went to HP support website, I entered my product model number "500-007a" and HP support website leaded me to my desktop's specification page (HP Pavilion 500-007a Desktop PC Product Specifications | HP® Customer Support). From this spec page, I can see my desktop's motherboard and sound/audio information there, but they are not very detailed.
    To highlight the audio part, I saw:
    Integrated IDT 92HD73E Audio
    Audio codec: IDT 92HD73E
    7.1 channel audio
    (The full information is in the website link above)


    My desktop's model number is "500-007a" and serial number is 4CE318OC7W.
    My desktop's series is called "HP Pavilion 500 PC Series"

    If needed, I will open my desktop. But once I opened it, how do I know if I have a pci sound device or an onboard device?

    Under the motherboard specifications u can see that it is an integrated(onboard) sound device. As it is not a pci, there is no possibility of bad contact.
    As others have suggested, if the sound device is not defect, it could be enabled/disabled via BIOS. But it seems u don't have this option.

    In your first message, u told bout installing SSD, this is a hard drive type. Didn't you open the case while installing this ?
    Did you change any jumpers (settings) ? If you did, it is possible that u have disabled the audio device by changing jumpers ??

    For the jumper:
    To make sure I actually did the right thing, I will state what I have done step by step:
    1) power off my desktop, then unplug the power
    2) open my desktop so I can see the motherboard
    3) On another laptop (this laptop has not problem at all, the audio problem is on my desktop), Google what a jumper on mother board looks like
    4) learned that a jumper may be something blue, and on the mother board around the the jumper there may exists some white text. The white text may be "CLR_CMOS".
    5) start looking for the blue jumper with white "CLR_CMOS" text around it.
    6) found it. it is blue and have white CLR_CMOS text around it.
    7) Take the blue jumper out from needle 1 and 2
    8) With out flipping side, place the jumper on needle 2 and 3
    9) Take the blue jumper out from needle 2 and 3
    10) With out flipping side, place the jumper on needle 1 and 2
    11) without closing the desktop box (I can still see the motherboard), plug the power, the power on my desktop
    12) The audio problem still remain, I can still see the red cross on the right bottom corner of the screen
    13) check device manager, still can't find the sound/game section

    I didn't change the jumper at all when doing the SSD upgrade. All I have done is unplug/plug HDD and unplug/plug SSD.

    Still think it just might be a missing driver for your sound in device manager. Unless you have something messed up in the wiring on motherboard. You were close to finding your sound drivers when you were on HP's site. I have 3 HP Computers. All desktops.
    Their is a Help section on HP's web site too. Where you can ask questions about anything to do with your HP Computer.
    Why you can't find any drivers from HP's web site is strange!!! As it scans your computer, and should list all the drivers and software available for your model. I would go back to HP's web site and try asking one of those tech's about your problem with no sound device showing in device manager. Here is a link to one of the help message area's. Talking about IDT Audio questions. Which is what you have installed in your HP computer.....same one I have....just different driver.
    http://h30434.www3.hp.com/t5/Desktop...s/td-p/2201361

    Once their, post a msg, and ask about your problem. Someone their might have a solution for this strange problem you have.

    Sorry to say it is looking more like a defective motherboard.
    No chance this rig is still under warranty?

    What is "the red cross at the right bottom corner of the screen"?
    Is the red cross over a speaker icon?

    I think the HP website will only find and display drivers for connected (installed) devices. So if the sound chip is not detected then you would not get any sound driver offered.

    The real clinching test for this kind of hardware problem is to run a version of Linux from a USB stick (this does not install Linux on your hard drive, it just runs from the thumb drive).
    If there is no sound while running Linux, and especially if there is no sound device found under Linux, then that would pretty much confirm that this is not a Windows or driver problem and it is likely there is a defect in the chip or the motherboard.

    You can search for and download a copy of Ubuntu or Puppy Linux to do this (two popular versions of Linux).
    Once copied onto the thumb drive you then use the PC's boot menu to boot from the thumb drive rather than the hard drive. You can check the HP site for instructions for which key to press while booting to bring up the boot menu.

    For my HP Computer, its the F9 key to TAP.....BEFORE you see any log on screen.

    Just keep tapping....do not hold the key.
